Thank for your quick response.
In a Wayland Desktop, the brightness can be changed normally. However, after
entering the Wayland session, the brightness in the TTY is always set to 255.
At this point, neither KDE tools nor brightnessctl can adjust the TTY
brightness anymore, so this appears to be a bug.
If you do not log into Wayland, then both the SDDM and TTY brightness can be
controlled successfully with brightnessctl.
